A new family of BINOL-based bis (bipyridine) ligands 1− 3 (BINOL= 2, 2′-dihydroxy-1, 1′- binaphthyl) was prepared in enantiomerically pure form. Whereas the coordination of zinc (II) ions to these ligands did not result in the selective formation of a specific metallosupramolecular aggregate, 1− 3 were found to undergo highly diastereoselective self- assembly to D 2-symmetric dinuclear double-stranded helicates upon coordination to ...
